CURRENT COLLECTOR FOR SOFC FUEL CELLS

摘要

The ferritic iron alloy is particularly suitable as a material for current collectors used in SOFC solid electrolyte high--temperature fuel cells. The material has a high chromium content upwards of 22% by weight, and a molybdenum content of 1 to 10% by weight. Additionally, there is provided 0.01 to 1.5% by weight of yttrium, rare earth metals, and/or their oxides. The alloy in particular has a high resistance to corrosion under the standard cell atmospheres in the temperature range from 700° to 900°C.
